SURGE ABSORBING COMPONENT TO PROTECT FROM OVERVOLTAGE AND OVERCURRENT

摘要

There is provided a surge absorbing component with protection function from overvoltage and overcurrent, comprising; a metal wire with high stiffness which has been mechanically and elastically deforemd is jointed with a low-melting point metal to a terminal or to a lead wire of a gap-type or microgap-type surge absorbing element. In case the surge absorbing element generates heat due to overvoltage and obercurrent, the low melting point metal is melt to separate from the terminal or lead wire, and the connection is broken. The stiff metal wire is connected in series with the surge absorbing element and a device or a circuit that is to be protected. 12
